Introduction

The DX Hub is a remote audio expansion hub that can be connected to an Allen & Heath SQ, Avantis, or AHM system, or to a dLive system fitted with a gigaACE card. It provides 4 DX ports to connect to DX Expanders, each port carrying 32x32 channels of 96kHz audio.
One DX32 or up to two DX168/DX164-W/DX012 expanders can be connected to each DX port allowing up to 128 remote inputs / outputs to be added to the system. With dLive, multiple DX Hubs can be used for further expansion or for dual redundancy.

information dLive requires firmware V1.6 or higher and a gigaACE I/O Port card to work with the DX Hub.

information SQ requires firmware V1.2 or higher to work with the DX Hub.

The DX Hub can be used free standing, or up to two units can be installed in a 1U rack space using our optional rack ear kit FULLU-RK19X, which can be ordered from your A&H dealer.
